Provided are a collapsible cup and a lid for sealing such cups. A collapsible cup includes a top cylindrical portion having a collapsible part and a sealing edge. The cup also includes a rigid bottom portion attached to the collapsible part and configured to move in and out with respect to the sealing edge by folding the collapsible part. The level of folding of the collapsible part determines different positions of the top portion, such as upper operating position corresponding to the maximum cup height, an intermediate operating position corresponding to an intermediate cup height, and a lower collapsed position corresponding to the minimum cup height. In the lower collapse position, the bottom portion may be substantially enclosed by the top cylindrical portion. The collapsible cup may include a reinforcement insert disposed within the top portion and used for engaging with a lid and providing support to the sealing edge.
